DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail based on an embodiment shown in the accompanying drawings.

FIGS. 1 to 4 show a first embodiment of the present invention, and a bathing assistance device A according to this embodiment.
The mat 1 has a seating surface portion 2 that can be detachably attached via a fastener such as a hook-and-loop fastener, and a size that can be stored in the bathtub B, and can be expanded upward by supply of tap water. Bellows bag 3, legs 4, 4, 4, 4 made of suction cups arranged at four corners of the bottom surface of bellows 3, and bellows bag 3
, A guide roller 6 mounted on the back of the bellows bag portion 3, and guide rail portions 7, 7 on which the guide roller 6 is rotatably mounted in a vertical direction. It is composed of a pillar 8 formed and a backrest 9 detachably attached to the back of the seating surface 2.

The mat body 1 is made of a plastic, such as foamed polyethylene, which has waterproofness and elasticity, and is formed in a mat shape, and a hook-and-loop fastener is provided on the lower surface thereof. Have been.

The seat surface 2 is formed in a substantially rectangular shape by a metal frame, and a surface fastener on which the mat body 1 can be detachably fixed is provided on an upper flat surface thereof. An upper surface of the bellows bag 3 is formed on the lower surface thereof so as to be fixed thereto. In this embodiment, the upper side portion of the front side portion of the seat surface portion 2 is formed to be inclined so as to protrude forward from the lower side portion, so that the leg does not hit when seated. Have been.

Further, the bellows bag 3 is formed of a tarpaulin and a bag which is vertically expandable and contractible.
Is moved up and down within a range of 209 to 600 mm from the bottom in the bathtub.

The legs 4,4,4,4 are composed of suction cups attached to the four bottom corners of the column 8, and the legs 4,4,4,4 are attached to the bottom surface of the bathtub. Thus, the bathing assistance device A according to the present embodiment is configured so as not to move unintentionally.

The bellows bag 3 is provided with a water supply / drainage device 5 including a drainage pump (not shown) and a hose connection port connected to the drainage pump. The other end of the hose H whose one end is connected to a faucet (not shown) is detachably connected to the hose connection port.

[0014] The drain pump is connected to the seat surface 2.
Activated when lowering to the desired depth position,
When the seat 2 reaches the lowermost position, the draining operation can be stopped automatically or manually by a hand switch (not shown). Also,
The rise of the bellows bag 3 is controlled by opening and closing a faucet.

The guide roller 6 is made of synthetic resin such as Duracon, and is turned up and down on each of the substantially inverted L-shaped bearings 10 protruding rearward from both ends of the rear side of the seat surface 2. It is pivotally supported.

The column portion 8 having a substantially L-shaped side surface is provided with a handrail frame portion 8A formed in an inverted concave shape.
And a substantially concave bottom frame portion 8B extending forward from the lower end of the handrail frame portion 8A, and the legs 4, 4, 4, and 4 are provided on the bottom frame portion 8A.
B attached. And the guide roller 6
Are slidably fitted along guide rails 7, 7 formed on opposing surfaces of both vertical rods 8C, 8C, each of which has a substantially C-shaped horizontal cross-sectional shape and constitutes the handrail frame 8A. Has been installed.

Further, the backrest 9 is provided with the seat surface 2.
A back support frame 9A extending upward from both ends on the depth side, and a corrugated back 9B made of foamed polyethylene which is detachably attached to the back support frame 9A.
It is composed of

Since the bathing assistance device A according to this embodiment is configured as described above, first, the bellows bag 3 is placed between the seat 2 and the legs 4, 4, 4, 4. Fix with fasteners. Attach the plumbing device to the bellows bag with a connector. The mat 1 is attached to the seat 2 by a hook-and-loop fastener, and the legs 4, 4, 4, and 4 are fixed to the bathtub floor. One end of the hose H is connected to the hose connection port of the bellows bag 3, the other end of the hose H is connected to a faucet, and the pump is powered from outside the bathroom. After this, fill the bathtub with hot water,
Open the faucet and supply water to the bellows bag part 3.

When the water supply from the bathroom is started, water flows into and accumulates in the bellows bag portion 3 and expands upward, pushing up the seat surface portion 2. 6 moves along the guide rails 7, 7 and stops the faucet when the seat surface 2 is flush with the upper edge of the bathtub.

In this state, the bather sits on the seat 2 and stabilizes the posture by immersing his legs in the bathtub.

Next, when the hand switch or the like is turned on to operate the pump of the water supply / drainage device 5, the bellows bag portion 3 is contracted by the drainage operation by the pump, and the seat surface portion 2 is lowered. Then, when the seat surface portion 2 sinks to a desired water depth position, the operation of the pump is stopped and the drainage is stopped. Thereafter, the above adjustment is repeated as necessary.

After the bather gets out of the bathtub, the drainage operation is performed by the above-mentioned pump, and after the seat surface portion 2 is lowered to the lowest position, the hot water in the bathtub is drained.

FIGS. 5 to 7 show a bathing assistance device B according to a second embodiment of the present invention. In this embodiment, the guide roller 6, the guide rail portion 7, and the support column in the first embodiment are shown. The part 8 is abolished, and the pantograph link 10 is disposed between the seat part 2 and the leg part 12 in such a manner that the bellows part 3 is held between the seat part 2 and the leg part 12. Other configurations and operations are the same as those of the first embodiment except that the configuration is such that they can be performed smoothly. Therefore, in the drawings, the same reference numerals as those used in the first embodiment are assigned to the drawings. Detailed description is omitted here.

That is, in the bathing assistance device B according to this embodiment, the pantograph links 10 in which the X-legs are connected in a pair in the vertical direction are arranged on the left and right, and the upper and lower rear ends of these links are connected. Except for the bending points, which are rotatably supported by the connecting bar 11, the X-shaped intersections are
And guide grooves 2A, 12A extending in the front-rear direction at the rear ends on both sides of the seat surface portion 2 and the rear ends of both legs 12, respectively, and are formed in the guide grooves 2A, 12A. The shafts 14 and 15 projecting from the upper and lower rear ends of the pantograph link 10 are slidably fitted.

Therefore, by turning on the hand switch and the like,
When the pump of the water supply / drainage device 5 is operated, the bellows bag portion 3 contracts due to the drainage operation by the pump, and the pantograph link 10 also contracts as shown in FIG.
The seat 2 descends. Further, when water is supplied into the bellows portion 3 by opening the faucet, the bellows portion 3 expands, and accordingly, the pantograph link 10 also extends and raises the seat surface portion 2 as shown in FIG. Since the seat surface 2 is supported by the pantograph link 10, a stable sitting comfort can be obtained.

In each of the above embodiments, as described above,
Since the mat body 1 and the corrugated back 9B to be laid on the seat 2 are detachable, maintenance such as washing and disinfection is easy.

[0027]

Since the bathing assistance device according to the present invention is constructed as described above, the structure and the mechanism are simple, the installation and clearing at the time of use are simple, and the lifting and lowering of the seat portion is possible. Because it is a system of direct water supply from the water supply and forced drainage into and out of the bathtub by a pump, fine adjustment is possible, and sanitary because hot water in the bathtub is not used,
In addition, the operation of raising and lowering the seat is only simple operation of opening and closing the faucet and the operation of the pump, so that the operation is very simple. It has many excellent effects such as easy maintenance.
